Abstract

Simulations of spectroscopic performances of CdTe detectors by means of a Monte Carlo code have been recently reported. The computer code was demonstrated to be an extremely useful tool in simulating the spectral response of CdTe to gamma rays and in understanding the detailed effects of physical and electronic parameters on the experimental performances. In the present work, the attention is focused on the various aspects of the CdTe response to Co gamma rays, in an energy range which is extremely interesting for practical applications of CdTe spectroscopy. Spectra are presented for different experimental conditions particularly in connection with the rise time distributions and with the spatial distribution of the electric field in the detector. A precise correlation is established between the energy distribution and the pulse rise time distribution: the spectra obtained by a selection of a particular rise time interval are presented and discussed, and the conditions for reaching the best energy resolution are indicated. These conditions depend on the material quality and on the electrical field distribution.
